摘要：

Recently, a demand for higher-than-ever strength steels has been increasing in machine structural application. Delayed fracture is well-established to be one type of hydrogen-induced materials degradation, and its complete prevention is very important to allow more wide-spread use of higher strength steels. Towards reduced susceptibility to delayed fracture, it is suggested that a control of grain-boundary property in steel, via impurity reduction and grain refinement, and also a change in carbide morphology are effective. In this paper, from the above standpoint, the authors have developed a new-type of delayed fracture resistant high-strength steel with 150 kgf/mm**2 tensile strength.
